Appiimion mea 'July 11, 1905. serial No. 269.205.

To all. whom it may concern:

Beit known that I, ANTON C. EGGERS, a citizen of the United States, residing in New York, in the borough of Brooklyn and State of New York, have invented certain new and useful Improvements in N ebulizers,- of which the following is a specication.

This invention relates'to nebulizers; and has as its primary obj ect'to provide im roved means for mounting and adjusting t e suction-tube embodied in such devices.

To this end the invention consists in a nebulizer embodying the novel features and combinations of parts which will appear hereinafter and finally be recited in the claims.

In the accompanying drawings, in which eparts are designated by the same reference characters throughout, Figure 1 is a side elevation of a nebulizer constructed in accordance withthe invention, and Fig. 2 is a vertical central section of the same.

Referring to the drawings, 1 denotes the liquid rece tacle or container, which may be of any pre erred form and is preferably made i zer, which is provi of glass,- as shown, being provided at its mouth with exterior screw-threads.

2 denotes the ca ed with a'cylindrical bore 3, having at its lower extremit a number of screw-threads which engage t e threads on the mouth of the rece tacle; as shown in Fig.

Said capis providJed at one side, slightl above the mouth of the liquid-receptacle, wit a lateral screw-threaded opening, into which -is screwed a laterall -extending air-tube the bore of which is closed at its inner end, while the outer end of said tube is connected in anv suitable waiy)r with the a1r pump orbulb which can e of any preferred form. The lower side wall of the air-tube 4 is provided with a vertically-extending screw-threaded opening, into which is screwed a second airthe upper tube 6, which extends downwardly from said first air-tube at substantially right angles therefrom and is provided at its lower or inner end with a hook-sha ed extension embod g a laterall -exten ing web or arm 7, ma e integral wit said air-tube. Said web or arm is provided at a point offset from vertical alinement with' the bore 8 of said airtube, which-bore extends downwardly onl to ortion of the extension an is there pr vi ed with a lateral opening 9, with of the improved nebulia vertically-disp osed screw-threaded openin 1n which ismounted a suction-tube 10, whlc is provided at its upper ortion with exterior screw-'threads engaging t ose of said threaded o ening 1n such a manner as to be vertically a justable. The upper end of the suction-tube 10 is preferably pointed, as shown, and may be adjusted in a'vertical direction relative to the lateral opening 9 in the air-tube 6, which opening is disposed at the same side of said air-tube as sa1d suction-tube.

It is obvious that the form of nozzle or discharge-tube which is used in connection with the im roved construction justdescribed 1s perfect y immaterial; but I have devised a nozzle of particular convenience and utility t e described. This nozzle (designated.

e drawings by the reference character 1 1) 1s preferably made integral with the cap 3 and extended upwardl therefrom, being 1n comfor use in connection with a nebulizer of the munication with t e upwardly-extending in.

termediate ortion of the passage or bore 13 of the lnozz e 11, which latter bore, like said nozzle, has the form of an inverted horseshoe, as shown, so that the discharge ends of said nozzle converge. Thev discharge ends are of such size and s aced at such a distance as to fit snu ly into t e nostrils ofthe person using the` ne ulizer.

The operation ofthe improved nebulizer is substantially the same as mother nebulizers vnow in use.v T he air being forced'from-the- A- Y.

bulb 5 upwardly through the laterally-extending air-tube 4 and downwardly from sald air-tubeinto the` vertical air-tube 6 passesA throu h the lateral opening 9 in said air-tube', where y an air-blast across the u per end of the suction-tube 10 is created. T s air-blast causes a vacuum in the suction-tube 10, whereupon the liquid contained in the rece tacle mounts rapidly in said suction-tu e until it isstruck by said 'air-blast. and formed thereby into a very ne spra which fills the upper portion of the receptac e 1 and is forced y the air-pressure generated in the bulb u wardly around the air-tube 4, through t e bores 3 and 12, and into the nozzle 11, which IOO separates the same into two parts which issue f from the discharge ends of said nozzle in convel'ing sprays.

e lmproved nebulizer has the advantage that the air tubes andsuction-tube are mounted in such a manner as to be readily removable when desired. The suction-tube is so mounted that the uality of the spray may be easily regulated y screwing this tube `either in upward or downward direction through the arm or web 7, so as'to vary the action of the air forced through the air-tubes.

Having thus described my invention, claim as -new and'desire to secure by Letters Patent- 1. In a nebulizer, the combinatiom with-a;I`

liquid-receptacle, of an air-tube extending downwardly throughthe mouth-of said recep tacle and provided at its lower end with a laterally-extendi ng arm, said airtube being provided with a lateral discharge-openn above said arm, and a suctionet'ube carried y said arm and adjustable vertically with respect to said dischar e-opening.

2. In ane ulizer, the combinationof aliq- @maar I cally-disposed suction-tube provided with eX- `terior screw-threads engaging those of said threaded opening, said suction-tube extending above said arm and into cooperative relation with said discharge-opening.

In testimon that Iv claim the foregoing as my invention 'have signed my name in presence of: two subscribing witnesses.
